To ai?. whom it may concern:

Be it known that I, Cani. Ciims'riaN Lansizx. residing at Sioux City, inthe county of ll'oodburv and State of Iowa, have invented a new and lin roved Villen-Stripping Maf chine, of whic the following is a specificalion.

My invention relates to improvements in I that t 'pe of machines that are especiallv designe( for stripping the bark from Willows that are used in the manufacture of iviilow baskets and it has for its object to rovide a machine of the character stated, o a simple and economical construction in which the willow is so manipulated or gripped dui-inv thereof through the mac iine that the bark is ef- K fectively removed, without the aid of scrapers. and in such mannerthat the willow a continuous lon itudnal passage is not iuarredacut or otherivise injured durin the operation of strgpin 4I3 invention compi ing in the willows and at. the Sametime crush the bark. brushing mechanism for tearing back or peeling the bark frein the Willow A combined with means for gripping the rom the stripped willow to dis-Charce it machine. that comprises yielding op iosing gripper members continuousl)- Inova le in one direction and so arranged to provide for a positive gripping of the willow at different. g in such inanncr that the gripi i or thin 1 thereof. i

points, an ping action is as positive at the ti end of the willows as at the butt en In its more subordinate features` my invention consists in cert-ain details of construction and peculiar combination of parte, Q all of which will be hereinafter fully described, and speciicaliy pointed out in tlieg appended claims. reference beinu' had to the i accompanying dran-in s, in whic Figure 1, is a longitudinal section of my improved construction of willow strippin machine. F ig. 2, is a top plan View thereo Fig. 3, is a detail side elevation of the brush mechanism and a portion of the discharging means. Fie'. 4, is a front elevation of a set of the combined feed and compressing rolls.

Fig. .'i, is a longitudinal section of a pair of i said drums carrying a series of transversely 105 sets ofthe said rolls. Fig. 03z is a detail view of a portion of the discharging means hereinafter referred to.

Referringr non:r to the drawings, 1 designates a suitable freine for supporting the en s au improved Y coperative arrangement of means for feed- E operating mechanism, at. the feeding in end Q of which is mounted a platform 2, on which l the willows are laid, butt end forward, as

they are fed into the machine.

Journaled in suitable bearings provided therefor on the frame, are a number of sets of combined squeezing and compressing rolls, each set of which consists of a pair of superimposed rubber rolls 3-3 mounted on the shafts 3*-3 the ends of which engage the frame bearings. In iractice, l use a immliciof sets of the ro s 3-3, six sets being shown in the drawing, in longitudinal alineincnt, and the upper ones of each set of rolls have gears h-1" that mesh with idle ears :5f-3 so as to impart a uniform forivar rotation to all the rolls, motion being transmitted to the rolls by an endless chain belt f1 that takes over a chain wheel 3 on the innermost one of the gears I?b and over sprocket wheel .52 mounted on the shaft 51 that forms a partof the discharging mechanism hereinafter set out and clearly shown in Fig. 3, by reference to which 'it will be also seen that the chain belt 4 passes over and transmits motion in the required direction to a sprocket wheel mounted on one ot' the shafts T2 that forms a part of the brush mechanism and imparts motion thereto. The rolls 3-3 act as feeder in rolls since they grip the willows and carry them forwardly through the machine and as the op using rolls of each set of rolls are lield closely contacting and with their shafts in relatively fixed positions it follovs that the willows, which are fed with the butt end into the machine, are tightly squeezed by the rolls 3 3, the squeezing action being of such character so as to thoroughly split nr break the bark on the willows, as the are being fed to the brush mechanism that removes the split, cracked or broken bark.

i The eeling or bark removing means colisists o two endless belts, an upper one T and a lower one 7*. that take over the u per and lower belt drums 4'1-71 inounte on i the shafts 72-72 suitably journaled at their ends in the main frame. cach of the dis osed brushes 'i3-73* of suitable niateruil that are caused to travel in the direc-- tion opposite to the movement of the willow,

by reason of the shafts 'T2-7? of the upper i and lower belt. drums being connected by
